I'd had several friends ask for a Brian May treble boost - so I figured I should get a few together - with a suitable Steggo twist, of course!
The board itself was laid out by South Obolon FX (Slava Ukraini!). As one would expect, this is not a terribly complex build. There are a few resistors, five capacitors, a circuit protection diode, and one transistor. For these initial builds, I'm using 1N5088 transistors, but it is likely the BC182L is the actual transistor used. I've built a socketed version of this board which I'm going to use to test various transistors to see what (if any) difference they make. All of the components are brand new sourced from Mouser - Yageo and KAO Speer resistors, WIMA and KEMET film capacitors, and Nichicon electrolytic capacitors. To make wiring the stomp switch easier - I'm using a PedalPCB 3PDT breakout board.
This is the first pedal I've built in a 1590B enclosure. These are smaller in all three directions from the 125B enclosures I'm used to. As such, I adjusted the locations of the jacks - and used lower profile 1/4" input and output jacks. I'd thought about adding battery functionality, but most people seem to simply use AC adaptors are large power supplies at this point, so I used the extra space for enclosure art instead!
I decided calling the Brian May treble boost "The Astrodon Physicist" with a night sky background would let me combine both dinosaur and Brian May references in on swoop, and I think the enclosure art (which is just a combination of licensed art) came out fairly elegant. For being such a simple circuit, this is a really nice boost pedal. I don't know if it is something that is going to be a permanent fixture on the pedal board, but it will certainly be in "heavy rotation."
